MOUTHPIECE-EOLLING MAbHINE:

Specification of Letters Patent.

Patented Sept. 2, 1913.

Application filed March 1, 1913. Serial No. 751,520.

To all whom it may concern:

Be it known that I, Hmson RAnowr'rzKY, a subject of the Elm eror ofRussia, residing I ilna, in the Empire of Russia, have invented a newand useful lVIouthpiece-Rolling Machine, of which the following is aspecification.

In known cigarette-making machines the mouthpieces forcigarette-wrappers were hitherto rolled up in the manner, that themouthpiece blank cut off from the continuous strip of mouthpiece forminmaterial was introduced between a man rel and a winding belt passingaround the mandrel, whereupon the blank was wound on the mandrel bymeans of the winding belt.

My invention relates to improvements in such cigarette makin machines,whereby the machine is simpli and the disadvantages connected with thewinding belt are avoided.

The chief feature of the improvement resides in this that the windingbelt is omitted and the continuous strip is itself utilized foryivinding the mouthpiece blank on the man rel.

I will now roceed to describe my invention with re erence to theaccompanying drawing, in whieh'- Figure 1 is an elevation of theimproved rolling-up device, a table being shown in section, and Figs. 2to 5 diagrammatically illustrate the various steps of the rolling-up ofa mouthpiece. Fig. 6 is a detail plan view showin the relative positionsof the mandrel an rollers carrying the strip of material.

Similar characters of reference refer to similar parts throughout theseveral views.

on a table 39 two distinct frames 10, '11 are shown to be disposed. Inthe right frame 40 a mandrel 4, two small guiding rollers 2, 3, twolarge guiding rollers 5, 21 and a cam disk 32 are mounted to turn. Thecam disk 32 is rigidly connected with a gear wheel 25, which 28 drivenfrom a main shaft 18 by means of a gear wheel 23 and an intermediategear wheel 24. The gear wheel 25 meshes with a gear wheel 26, which isri idly connected withthe large lower guidln roller 21. @n a pin 12provided in the rig t frame 40 a forked arm 28 is mount- 5 ed to rock,which is rigidly connected with a lower arm 29 carrying. a roller 30adapted to roll on the periphery of the cam disk 32. The forked arm 28carries a pin 27, on which an upper guiding roller 22 is mounted toturn. A pin 43 fastened on the lower end of the arm 29 is by means of ahelical spring 31 elastically connected with a pin 44 fastened on theframe 40. The cam disk 32 is for the greatest part of its peripherycircular and for the other part recessed at 45. The two arms 28, 29 areso set with regard to each other, that as long as under the pressure ofthe helical spring 31 the roller 30 rolls on the concentric portion ofthe cam disk 32 the guiding roller 22 supported by the forked arm 28 isheld at a certain distance above the eriphery of the lower guidingroller 21. hen, however, the roller 30 engages in the recess 45 of thecam disk 32, the helical spring 31 will by means of the two arms 29, 28press the upper guiding roller 22 a ainst the lower guiding roller 21.

On the eft frame 11 is fastened a pin 16 on which a lower pressingroller 8 and a two-armed lever 11 are mounted to turn independently ofone another. The roller 8 is rigidly connected with a ratchet wheel 9,in which a pawl 10 provided on the upper arm of the lever 11 is made toengage. On the main shaft 18 forming part of the cigarettemaking'machine (not shown) a grooved cam disk 15 is fastened and in its groovea roller 14 disposed on a lever 13 is made to engage. The lever 13 rocksat '16 on a suitable bracket 17 beneath the table 39 and is pivotallyconnected by means of a link 12 with the lower arm of the abovementioned lever 11. By means of the roll 14 the lever 13 is set toreciprocate from the main shaft 18, so that the pawl 10 feeds theratchet wheel 9 from left to right during half a revolution of the mainshaft 18, whereupon during the other half of the revolution the pawl 10rides over the backs of the teeth of the ratchet wheel 9, so that inthis manner the lower pressing roller 8 is intermittently turned.Fasteued on.the frame 41 is a pin 47, on which a forked lever 49 ismounted to rock, which by means of a pin 48 carries an upper prcssingroller 6 and is by means of a helical spring 7 elastically connectedwith a pin 50 on the frame 41. A paper cutting-off device of any knownconstruction is disposed on the left frame 11, which device is hereshown to consist of a stationary lower knife E19, a pin 51 fastenedthereon, and a mov- ;ahle upper knife 20 rocking on the pm 51 I andpressed against the stationary knife 19 i by means of a helical spring52 surrounding the pin 51. The movable knife 20 has a lower slotted arm,in the slot of which a pin '36 at the upper arm of a two-armed lever 37engages. The lever 37 rocks on a pin 38 provided beneath the table 39and carries at its lower arm a roller 53, which engages in agroove of agrooved cam disk 54 fastened on the main shaft 18. It will be seen, thatin this manner the movable knife 20 is caused to cut the paper once forevery revo- .1 is unwound from any roll (not shown) "and passes aroundthelower guiding roller" 2, the mandrel 4 and the upper guiding roller3.in the-manner clearly shown, then over the large guiding roller 5 andthe upper pressing roller 6 and between the two pressing rollers 6, 8,over the lower stationary knife 19 and between the two guiding rollers21, 22. The part of the strip 1 between the two pairs of rollers 6, 8and 22, 21 is assumed to be horizontal and the mandrel 4 is so disposed,that this horizontal part forms a tangent to' its lower side. The paperstrip 1 is supported during its passage between the rolls 6, 8 and the'spindle 4 by means of suitable tables, not shown in the accompanyingdrawings. The tension of the helical spring 7 is so adjusted as toprevent the paper strip 1 from shifting between the two pressing rollers6 and 8. The two frames 40, 41 are set at sucha distance from eachother, that a len th of the paper strip 1' suflicient for the ormationofa mouthpiece can be cut off at the moment, that the right end of thisblank just projects to the right from the vertical central plane of thetwo guiding rollers 21', 22, as is clearly shown in Fig. 5. The mainshaft 18 is made to run continuously, so that'all the gear wheels 23,24, 25, 26 and thereby the lower guiding roller 21 are made toconstantlyturn, while the paper strip 1 is on the contrary intermittently moved.-

When a length'of e paper strip 1 required for a mouthpiece moving fromthe cutting device 19, 20 (Fig.5) projects to the right from the twoguidingrollers 21, 22, it stops, whereupon the movable knife 20 isoperated for cutting off the blank. Immediately Y afterward by means ofthe roller 30 en aging in the recess-45 ofthe cam disk 32 t e upperguiding roller 22 is" pressed downward on the lower roller 21, so thatthe right end of the paper strip 1 isgripped. Then the lever 13 movesfrom left toright so that the pawl 10 ridesover the teeth of the ratchetwheel 9 and the paper strip '1 stops, see Fig. 2. At 'the same time thetwo guiding rollers 21, 22 during their rotation iii-opposite directionsmove the blank toward the mandrel, so that its right end engages be'tween the mandrel and said web. Onn secend and further rotation of' themandrel,

the end of the cut strip will be so covered up by the material that thesaid strip is well wound upon the mandrel and it will therefore beunnecessary to further guide its winding movement. At. the moment, thatthe right end of the blank is sufficiently gripped, the upper guidingroller 22 is by means of the roller 30'rolling on the concentric portionof the cam disk 32 again detached from the lower roller 21, so that theblank is released and is by means of the uncut paper strip 1 wound onthe mandrel 4, see Fig. 3. Meanwhile the movable knife 20 had turnedupward for permitting the paper strip 1 to move and the lever 13 hadcommenced its other stroke from right to left-,so' that the pawl 10 bymeans of the ratchet wheel 9 feeds the paper strip 1 forward, as isshown in Fig. 3. The right end of the moving paper strip 1 will engagethe'lower guiding roller 21 (Fig. 4), and when the blank has been woundon the man'- drel 4, the rightend of the paper strip 1 will project tothe required distance from the two rollers 21, 22, whereupon the paperstrip 1 stops and the cutting device 19, 20

is operated and immediately afterward the pressed downward for upperroller 22 is gripping the right end of the blank, as described above.

The rolled-up mouthpiece is in a known! manner pushedfrom the mandrel 4into a tube, over which the cigarette-wrapper is moved in order to beafterward taken ofl with the mouthpiece. This may be accomplished asfollows: As soon as the cut-blank has been wound on the mandrel 4 so asto form a mouth piece. it is shifted from the mandrel and introducedinto a cigaretteapper by a thin cylindrical casing or tube sliding onand along the mandrel, and preferably having less thickness than themouth PIG-C6 formed bygjthe rolled up blank or strip. To preventjastoppage of this cylindrical casing by the web of paper, the axis of theguiding roller 6 may be so arranged that it 18 not exactly parallel tothat of the guiding roller 5, but of alinement therewith. '-As theforward end of the cylindrical casing, during the positioned slightlyout contact with said strip, this forward end will be engaged by the webof paper, so that there is no danger of the forward border of the tubepushing against the border of the web-of paper. This action ispreferably restrained by guides, supports, or the like (not shown) whichcooperate with the mouth piece or with the cylindrical casing, and whichmay be operated in any suitable manner.

The rolling-up device can be varied without departing from the spirit ofmy invention.

I claim:

1. The combination with a mandrel, of means for passing a paper striparound said mandrel, means for gripping the paper strip after leavingsaid mandrel and intermittently feeding it forward, means forperiodically cutting a mouthpiece-blank off the strip, and means forperiodically gripping the cut blank and introducing its front endbetween said mandrel and the paper strip which is adapted to wind theblank on said mandrel.

2. The combination with a mandrel, of a cutting device, means forpassing a paper strip around said mandrel and between said cuttingdevice, means for intermittently feeding the paper strip, means forperiodi- 3.
